Our conferences provide the opportunity to hear the latest research in energy economics and dialogue that takes place between industry, government and academia. IAEE meets globally between three to five times per year. Don’t miss your opportunity to present your research.

Membership in IAEE is open to anyone worldwide who has an interest in the fields of energy or energy economics. Our membership consists of those working in both the public and private sectors including government, academic and commercial.

IAEE publishes three publications throughout the year. These are The Energy Journal, Economics of Energy & Environmental Policy and the Energy Forum. Members of the association receive these publications as part of their membership.

Abstract: Efficiency analysis of electricity distribution networks is often limited to technical or cost efficiency measures. However, some important non-tradable aspects of their service such as quality of service and network energy losses are often not part of the analysis. Moreover, technical or cost efficiency should not be achieved at the expense of allocative and economic efficiency. Valuation of service quality for regulatory models is particularly difficult. This paper presents an empirical approach to measure and incorporate service quality and energy losses into the analysis of technical and allocative efficiency of the utilities. We apply our method to the case of the distribution networks in the UK between 1990/91 and 2003/04 using the data envelopment analysis technique. We find that the efficiency of the utilities improved during the first and second five-year distribution price control reviews but exhibited a slight decline during the third review period. We find relatively low allocative efficiency � i.e. a mismatch in allocating resources among expenditures, service quality, and network energy losses. The results suggest that currently the utilities may not be correctly incentivised to achieve socially optimal trade-offs between these.
